Definitions

  • the present invention relates generally to collapsible containers but more particularly to a multi-purpose extendable and collapsible container with a hidden locking mechanism.
  • the present invention which will be described subsequently in greater detail, is to provide objects and advantages which are: [004] To provide for an improved extendable and collapsible container with a hidden locking mechanism allowing it to be locked at a desired volume. It is another advantage to provide a locking mechanism that allows a lid to be pressed on or pulled off without compromising the rigidity of the container.
  • the invention comprises a plurality of telescoping sleeves adapted to interlock with one another to form a desired volume.
  • a base member attached to a bottom most sleeve and adapted to house the sleeves when the container is collapsed, and adapted to form a base of the container when the container is extended.
  • a removable cap member attached to a top most sleeve and adapted to enclose the volume when the container is extended, the cap member includes a closable opening therethrough adapted to allow a substance to pass from the volume inside the container outward therefrom when desired.
  • a sleeve locking mechanism adapted to lock the sleeves in respective positions when a desired volume is formed and unlock the sleeves from their respective positions when it is desired to collapse the container.
  • the improved extendable and collapsible container has the sleeve locking mechanism housed within an interior of the volume formed by the sleeves.
  • the sleeve locking mechanism includes a control knob extending through the base member and outside the volume and adapted to allow the sleeves to be locked and unlocked therefrom.
  • the cap member further includes a spout portion attached to the closable opening and adapted to allow a smoother flow of the substance out of the container.
  • the spout further includes a stopper member adapted to selectively open and close the spout member.
  • the cap member further includes a nursing nipple attached to the closable opening, and a pressure valve attached to the closable opening and adapted to allow the substance to pass therethrough as the volume is reduced thereby causing an increase in internal pressure and thereby forcing a desired amount of the substance out through the valve.
  • the sleeve locking mechanism further includes a plurality of telescoping cylinders, each cylinder respectively attached to a telescoping sleeve.
  • a gear mechanism rotatably connected to an internal surface of the base member, mechanically connected to a lowermost cylinder, and rigidly connected to the control knob, such that the control knob is adapted to rotate the cylinders in either of two directions, one direction to lock the sleeves in place and an opposite direction to unlock the sleeves and allow the container to be collapsed.
  • the sleeve locking mechanism is formed as a straight bayonet type locking mechanism, wherein each the sleeve includes a series of bayonets on an outer surface thereof that releasably attached to an adjacent sleeve having a series of bayonets on an interior surface thereof, thereby attaching or releasing from an adjacent sleeve by a twisting motion of outer surfaces of the sleeves by a user in one direction to attach and an opposite direction to release the sleeves from one another and allow the container to be collapsed.
  • the sleeve locking mechanism is formed as a helicoidal bayonet type locking mechanism, wherein each the sleeve includes a series of bayonets on an outer surface thereof that releasably attach to a bayonet catch on the inner surface of an adjacent sleeve, thereby attaching or releasing from an adjacent sleeve by a twisting motion of outer surfaces of the sleeves by a user in one direction to attach and an opposite direction to release the sleeves from one another and allow the container to be collapsed.
  • the sleeve locking mechanism is formed as a ratchet type locking mechanism, wherein each the sleeve includes a series of first ratchet teeth on an outer surface thereof that releasably attach to a series of second ratchet teeth of an adjacent sleeve on an inner surface thereof, such that adjacent sleeves can be connected at various locations to one another via a linear motion of the sleeves by a user in one direction to extend the sleeves and form the volume and an opposite direction to collapse the container.
  • the sleeve locking mechanism is formed as a lip type locking mechanism, wherein each the sleeve includes an upper lip and a lower lip thereon, wherein each the upper lip releasably attaches to a lower lip of an adjacent sleeve, such that adjacent sleeves can be releasably connected by a user applying force to the sleeves in one linear direction to extend the sleeves and connect respective lips and form the volume and an opposite linear direction to disconnect the respective lips and collapse the container.
  • the improved extendable and collapsible container can be of varying shapes such as rectangular or cylindrical and is formed from a material chosen from a list of materials comprising steel, aluminum, and plastic.
  • FIG.1a-b Side view of the invention extended and isometric view of invention collapsed.
  • Figs.2a-b Isometric view of invention as a baby bottle and as a wine flask.
  • Figs.3a-b Isometric view of the base of the invention and cutaway view of cylinder type locking mechanism.
  • FIGs.4a-b Cutaway view of interlocking sleeves extended and collapsed.
  • FIGs.5a-b Cutaway isometric views of interlocking sleeves with teeth locking mechanism in fully extended position.

  • Figs.7a-b-c Partial view of straight bayonet type locking connection, exploded view of straight bayonet type locking connection and side cutaway view of helicoidal bayonet type locking connection.
  • An improved extendable and collapsible container (10) comprising of telescopic sleeves (12) that interlock when extended and having hidden cylinders (16) that also interlock such that a knob (17) provided on the base (14) of the container (10) be turned to lock the hidden cylinders (16) which in turn lock the sleeves (12) in place once a desired volume is attained.
  • a cap member (18) includes a closable opening (21), and fits on top of the container (10) and can have a plurality of functions such as a spout (20) as seen in Fig.1a or a nursing nipple (22) or a wine spout (24) with stopper (23) as in Fig.2a & Fig.2b.
  • the sleeves (12) interlock when two lip types interlock, a top lip (13) and a bottom lip (15) fit into one another as seen in Fig.4a.
  • the sleeves (12) are locked using a straight bayonet type (28) configuration interacting with a bayonnet catch (29) in Fig.7a & Fig.7b or a helicoidal bayonet type (30) configuration (as seen in Fig.7c) by twisting the sleeves in different directions, one way to lock and the opposite way to unlock.
  • the sleeves (12) are thicker where they interlock with the aforementioned locking means.
  • the container (10) with hidden cylinders (16) lock together when the knob (17) provided on its base (14) is turned in one direction.
  • a gearing mechanism (26) allows the knob (17) to control the hidden cylinders (16) thereby locking or unlocking the sleeves (12).
  • An alternate embodiment (Fig.5a & 5b) shows a ratchet type locking mechanism (21).
  • the cap member (18) further includes a pressure valve (19) to allow air to escape the container (10) when it is collapsed into a smaller volume.
  • Figure 3a shows the invention (10) in the form of a receptacle for storing semi solid contents (not shown).

Abstract

L'invention concerne un récipient extensible et pliant amélioré ayant une pluralité de manchons télescopiques qui s'imbriquent les uns dans les autres afin de former un volume souhaité. Un élément de base est fixé au manchon situé le plus bas et est adapté pour abriter les manchons quand le récipient est replié, ainsi que pour former une base du récipient quand le récipient est déplié. Un élément couvercle amovible est fixé au manchon le plus haut et est adapté pour fermer le volume quand le récipient est déplié, l'élément couvercle étant traversé par une ouverture refermable permettant le passage d'une substance depuis le volume à l'intérieur du récipient vers l'extérieur quand on le souhaite. Un mécanisme de verrouillage de manchon permet de bloquer les manchons dans des positions respectives quand un volume souhaité est formé et de débloquer les manchons de leurs positions respectives lorsque l'on souhaite replier le récipient.
